Weather Costs Golf Courses Money Every Week

Most tee time platforms show generic weather but can't tell golfers whether conditions are actually worth playing. Courses lose revenue, staff time, and repeat customers to preventable weather surprises.

🌧️ Rainout Revenue Loss

An average 18-hole course with 60 tee times at $65/player loses $15,000+ on a single rained-out day in refunds, cart fees, and food & beverage. Players who don't rebook are often lost permanently.

💨 Wind Blindspot

Wind above 15 mph significantly affects ball flight and scoring. Above 25 mph it's genuinely miserable. Generic weather apps show raw wind speed — not what it means for a round of golf.

📞 Manual Cancellation Calls

Pro shop staff spend hours calling and texting golfers before bad weather. That's $60–100 in labor per weather event — and players still show up unprepared half the time.

⛳ Lightning & Heat Risk

Golf courses face liability when players are caught in lightning or extreme heat. A composite playability score gives you a data-backed reason to delay or cancel a round.

✓ One Score Your Logic Can Act On

Temperature, humidity, wind, cloud cover, and rain combined into a single 1–10 golf playability score. Your tee time system checks one number.

✓ Golf-Specific Wind Scoring

Wind carries the strongest weight of any variable. Score drops sharply above 15 mph and is heavily penalized above 25 mph — because no golfer enjoys playing in 30 mph gusts.

✓ Automated Alerts Before It's Too Late

When the score drops below your threshold, trigger push notifications or emails automatically — before golfers make the 45-minute drive to a course in a thunderstorm.

✓ 7-Day Revenue Planning Window

Dynamic tee time pricing, tournament scheduling, and staff planning based on verified playability data a full week ahead — not a gut feeling.

How Golf Platforms Use This Data

One API call. Multiple revenue-protecting applications across tee time platforms, apps, and course management systems.

Automated Tee Time Alerts

When conditions drop below your threshold, trigger push notifications before golfers make the drive. Reduce no-shows and last-minute cancellations.

💰

Dynamic Tee Time Pricing

Charge premium rates on perfect scoring days. Offer discounts on marginal days to fill the tee sheet — especially valuable for public courses.

📅

Smart Tee Time Display

Show a playability score alongside tee times so golfers self-select into good weather windows — reducing frustration and chargebacks.

🏆

Tournament & Event Planning

Pick tournament dates around verified playability windows weeks in advance. 7-day data gives course operators a real planning window.

Built for Platforms, Apps & Operators

Our data is relevant anywhere outdoor golf conditions affect whether players show up, book, or compete.

📅

Tee Time Platforms

GolfNow, TeeOff, and similar reservation systems. Automate weather alerts, dynamic pricing, and cancellation logic at scale.

📱

Golf Apps

GPS rangefinder apps, scorekeeping, and course discovery apps. Add a weather intelligence layer to round planning and notifications.

🏆

Tours & Tournaments

PGA Tour, Korn Ferry, and amateur tournament organizers. Schedule events around verified playability windows and protect field commitments.

🎯

DFS & Betting Platforms

Daily fantasy golf and betting platforms. Wind and temperature are major scoring variables — 2.5km resolution data provides a genuine edge over generic forecasts.

Not Generic Weather — Tuned for Golf

Standard weather apps show raw conditions. Our index scores what those conditions actually mean for a round of golf — with wind carrying the strongest weight of any variable.

💨

Wind — The Strongest Weight

Wind carries more weight than any other variable. Score drops sharply above 15 mph — high wind fundamentally changes scoring, club selection, and enjoyment for every golfer.

🌡️

Temperature Sweet Spot

Peak score at 60–75°F — the range most golfers describe as ideal. Cold below 45°F and extreme heat above 95°F are penalized. Dewpoint scored separately for humidity impact.

🌧️

Rain Probability + Accumulation

Both rain probability and actual accumulation are scored separately. A 30% chance of drizzle scores very differently than a 30% chance of a thunderstorm.

☁️

Cloud Cover Matters Too

Partly cloudy (10–30%) scores highest — ideal visibility and comfortable temperature. Full overcast is penalized. Blazing sun at 96°F also scores lower regardless of cloud cover.
